PUNCHING AND EYELETING MACHINE.

SPECIFICATION forming part of Letters Patent No. 348,190, dated August31, 1886.

Application filed May 11, 1886.

this invention appertains to make and use the same.

The object of my present invention is to provide a punching andeyeleting machine of improved construction,which shall be efficient andserviceable for use, not liable to get out of order in the hands ofunskilled operators,

and which can be manufactured with economy and at comparatively smallexpense; also, to provide simple and convenient means in 'aneyelet-machine whereby the eyelet-delivering devices can be arrestedbefore reaching the point of delivery,to prevent the feeding of eyeletswhile the machine is running and punching holes, as hereinafter morefully explained; also, to provide means whereby the feed can be changedfor various spacing without derangement in the adjustment of thepunching or setting mechanism. These objects I attain by mechanism thenature, construction, and operation of which are illustrated in thedrawings and explained in the following description, the particularsubject-matter claimed being hereinafter definitely specified.

In the drawings, Figure 1 is a plan View .of a punching and eyeletingmachine embodying my invention. Fig. 1 is a plan view of thelower end ofthe eyelet-delivering chute, the receiving-set, and the eyelet-feedstop. Fig. 2 is a side elevation showing the mechanism, the side framebeing removed the better to reveal the working parts. Fig. 3 is ahorizontal sectional View at the line as m, Fig. 2. Fig. 4 is a planView of the end of the anvil-lever; and Fig. 5 is an outline view, onsmaller scale, showing a manner of arranging aspring in connection withthe eyelet-chute and its supporting-arm.

In referring to parts, A denotes the frame, formed in suitable manner tosupport the operating parts. B denotes the cam-shaft,

arranged in upright position and rotative in Serial No. 201,815. (Nomodel.)

bearings Z) I) at the rear part of the frame. D denotes the driveshaft,connected with said cam-shaft by bevel-gears G O, and provided with apulley, D,for the driving-belt, and with an automatic stop-clutch, D",of any suitable well-known construction, for clutching said pulley tothe shaft D, under control of the trippi ng-lever D" and treadle-rod D,which rod, it will be understood, is to be connected with a suitablefoot-treadle. These parts are so arranged that depression of the rod Dand lever D trips the clutch D and allows the pulley to rotate theshafts. Then when the treadle-rod D is released the clutch automaticallythrows off and stops the machine at a given position, substantially asin the usual manner of working machines of this class.

E E E indicate cross .bars or shafts, that serve as fulcrums for thevarious levers, which are confined laterally on said bars by suitablecollars or otherwise.

F indicates the punching-lever, carrying the punching-tool f at itsforward end, and centrally fulcrumed upon the anvil-lever G by the stude, while its rear end works in conjune tion with the cam F on theupright shaft 13, a suitable anti-friction roll or stud, f", beingemployed for engaging the groove of the cam. Said cam-groove is formedto give the lever an up-and-down action. The anvil-lever G is hinged orfulcrumed at its rear end on a vertical stud or axis, G, correspondingwith or adjacent to the operatingshaft B, in a manner to permit lateralswinging action of the front end of said lever, together with thepunch-lever supported thereon,and without interfering with thesimultaneous upward and downward operation of said punch-lever by itscam F. At its front end the lever G rests and slides upon the frame, asat 9, thus giving a firm support for the anvil G which is secured to thefront end of said lever G. The two levers F and G cross each other inthe manner illustrated in Fig. 2, and the work-supporting table H, whichis fixed on the frame A, is arranged between their front ends, asindicated, a suitable slot being formed in the table for theaccommodation of the punching and eyeleting tools.

G3 indicates a laterally-swinging lever for effecting sidewise movementof the anvil and punch. Said lever G is fulcrumed by an adjustable stud,G, upon a slotted bracket or ear-piece, A, fixed to the side frame A.Its front end is pivoted to a dependent lug, G on the anvil-lever, andits rear end works in conjunction with the cam G on shaft B. The leverG3 is slotted and provided with asliding fulcrum-block for the stud G.By changing the position of the stud backward or forward in the slot thelateral throw of the punch and anvil can be varied, and the feeding orspacing of the holes in the work regulated as desired.

I indicates the lower eyelet-setting tool, made in ordinary form, with acentral pin to receive the eyelet, and mounted in a verticallysuitabletreadle.

reciprocating rod, 1, thatis supported in bearings a on the front of theframe. Said rod and set are moved up and down by a lever, 1 fulcrumed onbar E, and operated by means of a crank, (I, connected with shaft D andworking in a curved slot in the end of said lever, as indicated bydotted lines, Fig. 2.

J indicates the eyelet delivering chute, mounted upon an upright lever,J, which lever is fulcrumed on the bar E", and is arranged to swingforward and back for the delivery of the eyelets onto the center pin ofthe settingtool I as it rises and falls by the action of a stud or roll,1 which is fixed on lever 1 and which works in an inclined slot, Jformed in the lever J, as indicated in Figs. 2 and 3.

The hopper J and means for distributing the eyelets into the chute J maybe of ordinary construction.

The hopper and chute are connected with their support in a manner to becapable of sliding backand forward thereon, and are retained normally atforward position bya suitable spring, .9, or equivalent means. A cut-offor stop device, having suitable means for operating it, is employedadjacent to the chute J, said device being arranged so that it can atany time be conveniently broughtinto position during the operation ofthe machine, for arresting the forward movement of the eyeletchute, orpreventing the end thereof from approaching the picker oreyelet-receiving set for the delivery of an eyelet thereto, thusallowing holes to be punched without setting eyelets therein. This stopdevice preferably consists of a reciprocating pin, K, that can be raisedin front of the chute, or to engage a lug, k, on the chute J, asindicated in Figs. 1 and 2, and thus hold the chute from advancing tothe position of the set. The elevation of said pin is in the presentinstance effected by a lever, K, and rod K, designed to be attached to a(Not shown.) The pin is depressed by a spring, K

L indicates the upper eyelet set or tool,which is fixed in the head of alever, L, that has its fulcrum on bar E, and its rear end working inconjunction with cam L on shaft B, the lever being provided with asuitable stud or anti-friction roll for following the groove of the cam,whereby the lever L is worked up and down. A setscrew and check-nut areprovided for adjusting the eyelet-set for different thicknesses ofstock, as at Z.

M indicates the presser-foot for holding the work on the table. Saidfoot is attached to the end of a lever, M, fulcrumed on bar E, andoperated by cam M for lifting said foot automatically at the time offeeding forward the work, The rear end of said lever is extended backpast the cam,and is connected by rod N with a suitable treadle, (notshown,) whereby the operator can lift the presser-foot for placing thework beneath it. A spring, m, connects the lever with a projectingportion,'a, of the frame for giving the required pressure and raisingthe rear end of the end rod, N, when the treadle is released.

1? indicates set-screws or adjusting devices for raising or lowering theshaft B and its cams L F, andthereby regulating the working of the upperpunching and eyelet-setting tools. An adjustable guide, h, is arrangedon the. table H for gaging the distance at which the holes are formedfrom the edge of the work.

R indicates a brake in combination with 'a wheel or surface, R,connected with the shaft 13. Said brake may be omitted, if desired.

The several cams are formed and disposed in a manner to give the desiredmovement to the levers at the proper times in the order of theirrotation, the operation of punching a hole, feeding forward the work,and delivering and setting an eyelet in said hole being accomplished ata single revolution of the shaft.

The operation is as follows: Assuming the pulley D to be running by theaction of the driving-power, the operator, by depression oftreadle-rodN, raises the foot M and places the work in position on thetable H, and allows the presser to rest upon it, then depresses leverD,which permits clutch D to take effect to cause the revolution of theshafts D and B, putting the cams and mechanism into action. The punchdescends upon the anvil, forming a hole through the work. The presser islifted, releasing the work, and the punch and anvil swinglaterally,carrying the work forward the distance of the feed or spacing.The presser then descends and the punch is raised and with the anvilreturns to its place. The eyelet sets then close together, and the chuteadvances in time to deliver an eyelet upon the picker or receiving-pinas it moves upward, and retreats in season to allow the sets to forcethe eyelet into the hole and there upset or clinch it. The sets thenreturn to place, and the clutch, having made its revolution, is trippedby its lug meeting the end of the lever, and is automatically thrown offand the machine stopped; or, if the lever D is retained depressed, themachine continues to run, and the operations as above are indefinitelyrepeated.

I am aware that combined punching and eyeleting mechanism in which thework is advanced or fed forward by the punching devices has heretoforebeen devised, and I do "not, therefore, herein broadly claim mechanismhaving such capabilities, irrespective of the peculiar construction andmanner of operation of the improved machine, as herein explained.
